DXF (Drawing eXchange Format) was developed by Autodesk in 1982 for AutoCAD and has been published as a public specification since its inception. It is primarily a 2D drawing interchange format (lines, arcs, polylines, text, dimensions, hatching), but also supports 3D entities: 3D polylines, meshes, surfaces, and ACIS-based solid bodies. DXF is the most universally supported CAD data exchange format in the industry — from CAD software to laser cutters, CNC routers, plasma cutters, and vinyl cutters. For 3D workflows, DXF is useful for transferring 3D wireframe models and extruded surfaces.
DXF is the lingua franca for cutting machines. Laser cutters, CNC routers, plasma cutters, and waterjet machines all read DXF for 2D cutting profiles and engraving paths.
DXF is the standard way to exchange 2D technical drawings between AutoCAD, ZWCAD, BricsCAD, LibreCAD, and any other 2D drafting tool regardless of vendor.
Architects share floor plans, section drawings, and site plans in DXF format for import into structural analysis, MEP coordination, and construction management software.
AutoCAD, BricsCAD, ZWCAD, LibreCAD, SolidWorks, Fusion 360, FreeCAD, Rhino, Inkscape, CorelDRAW, and virtually all CAD and vector editing tools.
For 3D conversion, DXF is used to export 3D wireframe or surface models for import into 2D/3D hybrid workflows, signage software, or CNC machine controllers.
